EPCRA Hazardous Chemical Inventory Reporting

Current understanding

Under EPCRA sections 311/312, facilities that store hazardous chemicals above threshold quantities must submit Safety Data Sheets and annual Tier I/II inventory reports to state/tribal/local emergency responders and LEPCs. EPA periodically updates reporting terminology and hazard categories to conform with OSHA’s Hazard Communication Standard (HCS), which itself aligns with the UN Globally Harmonized System (GHS). A 2025 EPA final rule conforms EPCRA reporting to OSHA’s 2012 and 2024 HCS amendments to improve consistency for facilities and first responders.

Evidence log

• 2025-11-18 — Fracturing Responsibility and Awareness of Chemicals Act of 2025: cross-connection with hydraulic-fracturing-sdwa-regulation: Both involve chemical disclosure regimes for industrial operations; FRAC Act would create a fracking-specific disclosure track parallel to EPCRA’s community right-to-know framework, including emergency access for medical personnel.
